Soft Pneumatic Actuator Skin with Embedded Sensors

Soft Pneumatic Actuator skin (SPA-skin) is a novel concept of ultra-thin (< 1 mm) sensor embedded actuators with distributed actuation points that could cover soft bodies. This highly customizable and flexible SPA-skin is ideal for providing proprioceptive ...

An experimental and computational analysis of primary cilia deflection under fluid flow

In this study we have developed a novel model of the deflection of primary cilia experiencing fluid flow accounting for phenomena not previously considered. Specifically, we developed a large rotation formulation that accounts for rotation at the base of t ...

Influence of molecular architecture on the isothermal time-dependent response of amorphous shape memory polyurethanes

John Christopher Plummer, Charly David Azra, Yaobo Ding

The thermomechanical response of a series of thermally activated shape memory polyurethanes (SMPUs), determined by dynamic mechanical analysis (DMA), has been adjusted by systematic modification of the molecular architecture. It is argued that the free rec ...

Dynamic mechanical analysis for rapid assessment of the time-dependent recovery behavior of shape memory polymers

John Christopher Plummer, Charly David Azra

Thermally activated shape memory polymers (SMPs) recover from a secondary shape induced by mechanical deformation to a primary equilibrium shape when they are heated to their actuation temperature. In certain applications, for example in the biomedical fie ...

High temperature transformations in a steel-TiCN cermet

Daniele Mari

The influence of the carbon content on the microstructure, phase transformation and hardness of an iron-based cermet is studied. The cermet is constituted by a high-alloyed steel as matrix, and TiCN particles (50 vol.%) as reinforcement. The material is pr ...

Thermo-mechanical fatigue behaviour of welded tubular parts made of ferritic stainless steel

Roland Logé

Car exhaust manifolds are critical components subjected to cyclic thermo-mechanical fatigue (TMF) during function. To reduce design costs, robust numerical design tools are required to assess their behaviour and lifetime. Manifolds are constructed by weldi ...

Shape memory polymers with controlled time-dependent shape recovery

Charly David Azra

The aim of this thesis has been to investigate the use of heat-activated shape memory polymers (SMPs) as novel smart actuators for the controlled delivery of fluids and their suitability for applications such as low-cost drug delivery. On heating to temper ...

Long-Term Development of Thermophysical and Mechanical Properties of Cold-Curing Structural Adhesives Due to Post-Curing

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Omar Moussa

The long-term changes in the thermophysical and mechanical properties of a cold-curing structural epoxy adhesive were investigated by accelerating the curing reaction by post-curing at elevated temperatures. Experimental data concerning the glass transitio ...

Grain boundary formation stages in a deformed yellow gold single crystal studied by mechanical spectroscopy

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

A monocrystalline 18-carat yellow gold sample is deformed stepwise from 2% to 12% at room temperature. The mechanical loss spectrum is recorded and analysed. At low deformations the exponential high temperature background increases. At a critical deformati ...
